Investigation of the performance of a large‐diameter conventional motionless mixer used as a continuous reactor for styrene polymerization showed that it behaved adiabatically. Computer simulation (in which the mixer is treated as an ideal plug‐flow reactor having perfect radial mixing) predicts this tendency in terms of axial temperature profile. To avoid adiabatic polymerization, with its attendant problems of plant operability and polymer quality, the use of motionless mixers having internal heat transfer surface is indicated.
